ROTARY sAW GUARD.

Application filed August 5, 1924.. Serial No. 730,312.

This invention relates to guards for rotary saws and has for its objecta particular simple and efficient means by which the operator is warnedby his hand or fingers coming in contact with two guard members beforehis hands can come in contact with the saw.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed and table, the guardmember being arranged in front of the saw so as to engage theworkincludes a second guard member arranged on one side of the body andmovable vertically, the second guard member also extending in front ofthe saw. 7 j

1 designates the rotary saw which may be of any suitable form, size andconstruction.

2 is the work table, the saw projecting through and above the table inthe usual manner.

3 is the body of the saw guard, it being shown as carried by an arm 4pivoted at 5 to a suitable support 6 and having a weight 7 which tendsto counterbalance the body 3 so that the guard readily lifts off fromthe table when desired. The weight of the body is slightly greater thanthe weight 7, so that the body tends to rest on the table.

The body is here shown as formed with double or spaced apart walls 8between which the saw extends.

The guard member at the advance end of the body 3 is a wheel or roller 9arranged between the walls 8 and movable vertically relatively to thebody, it being here shown as having axles 10 arranged in vertical slots11 in the body.

12 is a second guard member mounted on one side of the body 3 or on theside on which the workman stands when attending the saw. The guard 12 ismounted to move vertically and is here shown as elongated and as restingon the table 2 and extending in front of the saw 3, and lapping thewheel 9. A

The guard 12 is also preferably formed with vertical slots 13 forreceiving pins or studs 14 on the body 1, the ends of the studs beingshown-as connected by a strap 15. Preferably the body also supports aseparator strip or kerf spreader 16 adjustably secured thereto by afastening member 17, this separator strip extending into the cut made bythe saw in order to separate the piece sawed off from the board or otherpiece of work.

In operation, the board 18 is fed to the saw and pressed under the wheel9, the wheel moving vertically in the slotsi-ll. As the board is fed tothe saw, it also engages the lower edge of the guard 12 andlifts itrelatively to the body 3. In the event, the operator has his hands onthe work as it feeds to the saw, his hand will first engage the wheel 8and if then he continues to maintain his hold on the work, he willreceive a second warning by his hand coming in contact with the secondguard 12.

19 is a rest pivoted at 20 to the front end of the body 3 and arrangedto be moved from the inoperative position shown in full lines, Figure 1,into its operative position to engage the table 2 and hold the body 3 inan elevated position as shown in dotted lines.

The guard 12 as here shown is formed with an opening 21 through which,when the body 3 is in its elevated position on the'rest 19, the operatoris enabled to determine the width of the cut to be made when resettingthe gage block Without removing the saw guard.

l/Vhat I claim is:

1. The combination with a rotary saw,

' and a work table, the saw projecting through the table; of a workguard arranged above the table and over the saw and arranged to be movedvertically relatively to the table and the saw and a rest carried by thebody and movable from an inoperative position into a position to engagethe table and to hold the body in an elevated position.

2. The combination of a rotary saw, and a work table, the saw projectingabove the work table, of a guard comprising a body arranged above thetable and the saw and. having spaced apart walls providing a slotlengthwise thereof into which the sawprojects, a guard wheel carriedbythe body in said slot in front of the saw and arranged to rest on thetable and the. work, the wheel being mounted to move verticallyrelatively to the body, a second guard carried by the body along oneside near the bottom there of and being mounted to. move vertically.

combination of a rotary saw, and

a Work table, the saw projecting above the.

work table, of aguard comprising a body arranged above the table and,thesaw. and having spaced apart walls providinga slot lengthwise thereofinto whichthesaw pro: jects, a guard wheel carried bythebody in saidslot in front of the saw and. arranged torest onthe table and the work,the wheel being mounted to move vertically relatively tojthe body,atkerf cutter. adjustably mounted in the back portion of the slot insaid bo.dy,,said kerf cutter extending below the work table, a secondguard carried by the ,bodyalong one side-near the bottom thereof andbeing mounted to be moved vertically relatively to the body, the secondguard extendingin front of the sawnand being pro vided with an opening,and. a rest carried by the bodyand movable from an inoperativepositioninto a position to engage. the table and to holdthe body in anelevatedposition.

In testimony. whereof, I have hereunto signed my name, atSyracuse,intthecounty of Onondaga, and State of New York, this th day of July,1924.
